Description
Technical field
The present invention relates to a kind of printing ink, and in particular to a kind of printing ink of high-solid lower-viscosity degree and preparation method thereof.
Background technique
Ink is important materials used for printing packaging materials, it is expressed the pattern and text on stock by printing.
It is chlorinated polypropylene ink, polyurethane ink, polyacrylic acid ester oil that in China, usage amount is maximum at this stage, in printing packaging
Ink, containing organic solvents such as a large amount of benzene, toluene, butanone, ethyl acetate in this kind of solvent-based ink, in solvent-based ink
In use process, the solvent contamination air of volatilization endangers the health of operator, the residual solvent meeting in packing articles
Food in serious pollution packaging, therefore the research and development for carrying out environment-friendlyink ink are imperative.
China generally acknowledges that more environmentally friendly ink is water-based ink at this stage at present, low volatilization, high-environmental, less harmful,
The advantage of high-quality is increasingly favored by people, but domestic current water-based ink development and incomplete, almost without true
The water-based ink of positive compound intaglio printing, there are problems for existing water-based ink, such as solid content is low, viscosity is high, solid
Change the disadvantages of speed is slow.
Summary of the invention
In order to overcome the part of background technique insufficient, the present invention provides printing ink and its preparation of a kind of high-solid lower-viscosity degree
Method.
The technical scheme adopted by the invention is that: a kind of printing ink of high-solid lower-viscosity degree, by weight percentage, the height
Gu the printing ink of low viscosity includes following components:
Water-based acrylic resin: 40-50%,
Pigment: 10-20%,
Plasticiser: 2-5%,
Levelling agent: 0.5%,
Antistatic agent: 1-5%,
Trifunctional urethane acrylate: 20-30%,
Coupling agent: 1%,
Defoaming agent: 0.5%,
Crosslinking agent: 1%.
Further, the pigment passes through modification, the method being modified are as follows: water is added first in pigment and carries out
Stirring, then adds molybdenum disulfide powder and ethyl alcohol, pours into stirring container and be sufficiently stirred 30-40 minutes together, add
Between carboxyl benzene sulfonate, continue stirring 15-20 minutes, obtain mixed emulsion；Lotion is finally poured into vacuum ball grinder and is placed in ball
Grinding machine carries out planetary vacuum ball milling；Finally, the pigment after drying materials are modified is taken out in pressure release.
Further, wherein the ratio of pigment, water, molybdenum disulfide powder and ethyl alcohol is 100:5~20:5:60~70.
It is handled by the above pigment modification, improves the viscosity of ink, accelerate the drying of ink, guaranteed equal when printing
Even densification improves the comprehensive performance of the ink of ink, it is opposite with there is higher solid content, lower dense for common ink
Degree, wherein solid content is higher by 20-30% for common water-based ink, while viscosity is lower.Wherein molybdenum disulphide powder
End, water and ethyl alcohol, improve the mixed uniformity of pigment, reduce the viscosity of ink, and molybdenum disulfide powder therein can add
The grinding of fast pigment improves ink adhesion so that fine pigment partial size, increases the contact area of ink and substrate.
Further, the trifunctional urethane acrylate is made of following methods: first will be by six methylenes
Group diisocyanate tripolymer, hydroxypropyl acrylate, dibutyl tin dilaurate, hydroquinone are uniformly mixed to get mixture,
Then mixture is put into reaction kettle and keeps being heated to 60 DEG C, continue 2 hours.
Urethane acrylate is that light consolidates the important basic resin in field, and the urethane bond energy contained forms a variety of hydrogen bonds,
It can be improved wear-resisting property, flexibility, temperature tolerance and the adhesive ability to substrate of solidfied material, the present invention is by being added trifunctional
Urethane acrylic can be modified ink, improve ink comprehensive performance, especially adhesive ability and solidification rate.
The usual way of prior art preparation urethane acrylate is to utilize isocyanate group in polyisocyanates and more
In first alcohol hydroxyl translate, and using hydroxyl acrylate introduce activity group, prepared ink have complex process,
The disadvantages of low and rate of polymerization of photopolymerization reaction activity is slower, and often occur solidifying incomplete phenomenon in the curing process.This
The method and process that invention prepares trifunctional urethane acrylate is simple, and helps to improve rate of polymerization.
Further, the coupling agent includes methyltrimethoxysilane, dimethyl diethoxysilane, phenyl three
In Ethoxysilane, hexamethyldisilazane, 3- glycidoxypropyltrime,hoxysilane or vinyltrimethoxysilane
Any one or at least two combination.
Further, the crosslinking agent is ammonium carbonate zinc and/or ammonium carbonate pick.Ammonium carbonate zinc and ammonium carbonate pick belong to nothing
Machine crosslinking agent can be reacted with resin and carboxyl, can generate zinc ion key or pick ionic bond, these ionic bonds have very strong resistance to
Hot and alcohol resistance can greatly improve the chemical stability of ink, improve the adhesive force of ink, be not easy to be oxidized.
Further, the defoaming agent is organic silicon defoaming agent, and the defoaming agent includes that moral modest 6800 and/or moral are modest
6500。
A method of preparing the printing ink of high-solid lower-viscosity degree, comprising the following steps:
Step 1: water-based acrylic resin, pigment being mixed according to the ratio and trifunctional urethane acrylate is uniformly mixed to get
Mixed solution a.
Step 2: coupling agent, crosslinking agent, levelling agent, antistatic agent being added according to the ratio in the mixed solution a that step 1 obtains
Mixed solution b is obtained with plasticiser, mixed solution b pours into the blender with heating function to be thoroughly mixed 2-4 small
When.
Step 3: completing in step 2 and then be added to stir 1-2 hours in blender by defoaming agent to obtain solution c.
Step 4: the solution c in step 3 being poured into ball mill and is ground 5-8 hours, until last granularity reaches 0.5
~2 microns obtain the printing ink of final high-solid lower-viscosity degree.
Further, the temperature of blender controls 50-70 DEG C in the step 2, the control of the revolving speed of blender 2500~
4000 revs/min.
Further, at 25-40 DEG C, the revolving speed of blender is controlled in 1000- the control of blender temperature in the step 3
1500 revs/min.
The beneficial effects of the present invention are:
1, of the invention that processing is modified to common pigment, the viscosity of ink is improved, the drying of ink is accelerated, guarantees print
Even compact when brush improves the comprehensive performance of the ink of ink, opposite to contain admittedly with for common ink with higher
Amount, lower concentration, wherein solid content is higher by 20-30% for common water-based ink, while viscosity is lower.
2, the present invention joined molybdenum disulfide powder, water and ethyl alcohol when modified, improve the uniform of the mixing of pigment
Property, the viscosity of ink is reduced, and molybdenum disulfide powder therein can speed up the grinding of pigment, so that fine pigment partial size, increases
The contact area of big ink and substrate, improves ink adhesion.
3, the present invention is capable of providing more light reaction groups double bond by addition trifunctional urethane acrylate,
To enhance light reaction, crosslink density increases, so substantially reducing the curing time of ink.
